Jesus: perfect? Discuss!

A friend threw me a theological poser on Facebook today. (My friends know I like such things!) Here it is:

Having a few musings today..... Jesus/God was perfect, right. Ok good, Jesus also has been through everything we go through and knows what it is like. However feelings like - envy, jealousy, pride, unforgiveness - we would consider to be sinful. So then could Jesus have ever felt those things if he was in fact perfect - without sin? Did he know what it was like to feel those things? And further is it the feeling that is sinful or in fact the action that comes from it? - Discuss.

And here's my brief reply:

Interesting question. Touches on some deep and mysterious stuff about the incarnation. If Jesus' humanness was genuine (which we absolutely believe it was), he must have had weaknesses: his 'perfection' didn't preclude them. He was afraid (Gethsemane), he was grieved (Lazarus), angry (especially with the Pharisees), exasperated (especially with his followers). He got hungry, tired, hurt. I think he must have had feelings prompting him towards envy, jealousy, pride, unforgiveness... But as you say, the crucial difference is that he didn't let the feelings (temptations if you like) harden into attitudes. As for his perfection - the book of Hebrews says he 'learned obedience', which implies his perfection was not a static state like a marble statue, but again a human reality, something he matured into as he made holy decisions.

Would you have added anything? Or said it differently? Or said something else entirely?

And here's another question for the keen. In our thoughts about Jesus, do we tend towards overemphasising his deity or his humanity (or do we get the balance right)? And what might be the implications of this (either way)?

As my friend said: 'Discuss'!
